Many of my more advanced packages use a sophisticated plugin mechanism for easy expansion, both within the package and across packages. If you are already a user of my packages, you may already have met this documentation system in the 'plugins' dashboard pages such packages provide.
Built in Documentation
The plugin system includes built in documentation.
Package Magic is primarily a dashboard tool. Nevertheless, since v1.1.8 Package Magic has included a block that can be used to create documentation pages for any use of my plugin systems on the front end of a site. That block is used on this site to provide the latest documentation for Package Magic and other addons.
